This is a Request for Information (RFI) only, not a solicitation for quotes, and it does not commit the government to a future contract. The 420th Instrumentation Group is exploring solutions for a Ground Power Unit (GPU) with highly detailed technical specifications, including specific electrical outputs, weight classes, and environmental operating ranges. The GPU must be capable of supporting aircraft start-up and be mounted on a towable trailer that raises the unit 18 inches off the ground. Responses, which should outline commercial solutions, will be used for planning purposes and will not be evaluated as proposals. All responses and associated costs are at the respondent's expense and should be sent via email to the provided points of contact.
